Viega 50602 PureFlow Zero Lead Manabloc Valve Stem Replacement Kit Red and Blue

I've used these kits to replace several of my leaking older style valves. Here's how I do it: 1) Shut off water supply to house. Open all fixtures to allow water to drain. It takes a while. 2) Use side cutters to shorten one side of the blue or red valve cover. Rotate valve 180° so cut side is closest to center of manifold (valve in on/open position). 3) Peel off the colored connector. 4) OPTIONAL: Shut off all valves except the valve being replaced. This will prevent water from gushing out from those tubes and limits water to the circuit being fixed and water in supply line and manifold. The risk is potentially causing leaks from another valve. 5) Position steel valve remover tool behind valve to be removed. I do not remove any of the PEX tubing. It's a little tricky and I have smaller hands but I can get the job done without disturbing the connections. 6) Pull steel tool toward you until it stops. You'll feel the valve move toward you a bit. Every one I've done has moved easily (make sure valve is in ON/OPEN position). 7) Lightly lube new valve with food safe o-ring lube. This step is optional but may prove to be helpful down the road. 8) Pull valve out with pliers. It should come out pretty easily. Be prepared for water to possibly gush out. 9) Insert new valve. It should slide in and click into place pretty easily. I do this quickly if water is coming out after removing old valve. 10) You're done!

Item works perfectly and will buy from again

My home builder installed MANABLOC water manifolds that distribute water to each faucet, toilet and waterlines throughout the house. When it cam time to fix a faucet by first turning off the water to the faucet, I found that the MANABLOC individual valve was leaking. Searched online how to fix and found a YouTube video showing how to replace the valves on a MANABLOC water manifold. It also mention where to get these valves on Amazon. Super please that I could find the parts and fix it myself. The instruction and pretty easy. From this kit use the level on the back and push the valve out toward the front. Then remove and install the new valve by pressing it in. The hard part is the water dripping from the line even after you turn off the main water to the house. Its a small amount of water that you can catch using several rags. Once the new valve is installed, it worked perfectly turning off the water to the faucet.

Worked great but the turn nipple is a different size than the old version so you need two different tools now. A smaller one for the old and a bigger one for the new

One of the rare home-repair projects that can be completed as easily as the Youtube videos suggest. Definitely manageable and cheaper than a plumber.

For the first time in a long time, a repair went like it was supposed to. The included removal tool literally made it a "snap". The online video was easy to follow (as well as several other handyman videos) and made it easy to DYI.

I had the older valves on my Manabloc and the tip was smaller and broke off in the original key. I ordered this kit after making sure the valves would fit. I watched the video and was able to replace my valve in about 15 minutes, which included the time it took to turn off the water main and drain the manabloc.

I’m sure it’s a fine product, just doesn’t fit my older system. Can’t attest to its durability, so I gave it an average rating.
